What's the difference between a Layer 2 & Layer 3 switch
A L3 switch also does switching exactly like a L2 switch. The L3 means that it has an identity from the L3 layer. Practically this means that a L3 switch is capable of having IP addresses and doing routing. For intra-VLAN communication, it uses the MAC address table. For extra-VLAN communication, it uses the IP routing table.

I use 2 computers & 2 simple switches each switch connect to one pc & between both switch I connect 2 wires for check redundancy.

Why is there flooding on L2 but not on L3? - Server Fault
2015年4月29日 · @Jimmy88 because in the hub-age of networking (and before) there were very few switches. Generaly every packet went everywhere. So there was no need for another protocol. And it's way simpler to implement (especially important for small dumb $10 switches; back in the days for every switch) than separate protocol –
firewall - VLAN ACLs and when to go Layer 3 - Server Fault
If you need to route IP between different subnets then you need a router. It could be an embedded layer 3 entity in a switch, or it could be a "router on a stick". Anything that can route IP between different subnets is a router. re: ACLs - Like I said in #1-- I'd be wary of a device that did "quasi layer 3" functions.
Can a VoIP or an L2 switch prevent a PC from accessing a network ...
